Each. of the ucts, for instance 4:, s lineally' inovcon able; and there are two independent deyices which engage it and which act in opposite directions thereon to adjust it'and lock it in adjusted position; .Prelerably.

these adjusting devices are in theffo rm of .ment of the inventi'on these screwsare held against longitudinal movement and: have threaded engagement directly with thee on:

Inasmuch as. the "two ia-Wt member is heldfirom rotation within nally and'locked in adj ustcdp ositionj lWhen the screws have directthreaded engagement with the contact member, as shown, 'it is necessaryto hold; them against longitudie nal movement.

In orderto provide a simple and comp ct construction, this opening consists of two: intersecting 7 bores 15 and'lfi, one adapted to receive and, the contact memben and the other adapted toreceiye and fit/the exteriors of the bores intersect, a sector of the contact'mem-' bcr is concaved and is threaded along the enga ed by the screws,; whereby the coni the gauge and may be adjustedlongitudi:

' The provision'of the twopins l7 and18, one for each screw, is of great importance. If only a single pin were provided for both screws and such'pin became loose, the conttct'merhber would be allowed to move therewith, since the pin abutment is the only means holding'themember in place.

However; with the present two-pin arrangement; if one pin does become loose it does,

not" affect the "acciiracy of the gauge since the bearing of each screw on its pinis, al-

is entirelyjseparate from theothenf v I If it is desired to lad usta contact memthe screw- 14' then screwed-inward. e ince -ways in the same direction and each 'pin the] "screw. It ;cannot 1 move longitudinally inward mthin the bore because'of' ts 'seat-- turning of the screw is to drawthe gauge member t out of the bore; WVhen properly? adjusted the" member may be locked bytightening the screw 13. If it is desired .to'move the member outward-the screw 14; is" tirstloosened and the screw 13 screwed -.inwal'd, the general operation being the sameas above described.
